A window popped up and proceeded to run a "scan" of my drive and showed me about 4 dozen infections, which are no doubt bogus.

Regrettably I had McAfee disabled for the last few days ( I write online games and every new exe compile causes McAfee to complain ). I re-enabled it and it killed the process av.exe, but it left my system in a hosed state where none of my desktop shortcuts worked. I found the fix ( apparently the trojan turns EXE into an unassociated file type )

What I'm wondering here, if McAfee could give me some feedback here, is whether they know what the trojan DOES. Is this a key-logger, password stealer or simply an extortion racket designed to get people to pay for bogus virus removal?
